How to fix RA29 fuel sender!

I pulled the fuel pump from my brother’s 77 liftback to replace the pump, and tested the fuel sender as well. Of course it was erratic.

The coiled resistance wires tested good and I found out the grounding point between the moving rod and the frame was the failure. Likely a result of the corrosion.

I soldered a wire to the contact arm and grounded it through a bolt, and that completely fixed it!
